Anyone know how to know what code the computer is throwing without using a diagnostic computer?

Depending on what year your Jeep is, you should be able to get the odometer to cycle through any codes by turning the key between Off and Run 3 times (IE, on the third time you switch it to Run, leave it there for a few moments and watch the odometer).
